This ford is a zx3...It started throwing codes for secondary air intake, mainly "low flow" to left port and for secondary air one way check valve. This leads me to think I need to replace the check valve but nowhere can I find anything to tell me where it is . Can you give me a location and will (for example) a universal one from auto zone work. I also read online that a couple people drilled a small hole in the bottom of the blower to avoid condensation from going into the engine? Supposedly no more trouble>

If I remember correctly p491 and 492, code reader saying "insufficient flow bank 1(left bank) and 492 "one way check valve". The car started having a problem starting this morning so I cleared the codes and started right up. Maybe coincidence.

OK, tell me if I'm wrong.....picture 1 shows secondary air pump under front bumper/passenger side. Picture 2 shows secondary air one way check valve connected to engine on right side(red arrow)?? According to code reader just check valve may be the problem.

the solenoid may be the problem or not, could be no power to it as well so check for a fuse or relay under hood that may not be working. third pic shows why codes is set
